this tool is almost useless for us now. To setup any custom profiles which would UC would cause severely degraded performance. Also switching governors is not a good idea either in the main profile as you'll also see performance degradation. You want it to scale between 245760 and 600000 on a ondemand governor which is what it is by default.
The only change i personally made in the app is to switch the main screen to 122880 min. Also i set a profile for screen off of min 122880, max 245760 and changed that gov to conservative.
cheers.
